application led October 6, 1919. Serial No. 326,609.

Toall whom it may concern Be it known that ll, CLIFFORD RICHARD VAN DUSEN, a subject oit' the King of Great Britain, and resident of 310 Clendenan Ave., in the city of Toronto, county of York, Province of Ontario, in the Dominion of Canada, have invented: certain new and uset'ul lmprovenients in Sanding Devices, of which the following is a specification.

The invention relates to improvements in sanding devices as described in the present specification and shown in the accompanying drawings that form a part of same.

rl`he invention consists essentially of the novel features of construction whereby sand or other similar material is delivered to the road surface directly in advance of the vehicle wheels. j

'lhe objects of the invention are to eliminate skidding of the vehicle and thus prevent accidents, to provide 'a sanding device which will be instantaneous in its action, to provide a device which will be neat and attractive in appearance and which may be.

adapted to any form of vehicle and gener.

ally to provide a sanding device which will be inexpensive of construction, ellicient in operation and durable.

Vln the drawings, Figure 1 is a side view of a portionof a car with the device in position thereon, a portion of said car being broken away to disclose the operating means.

Figure 2 is a plan view trom the under side of the car.

Figure 3 is an enlarged longitudinal sec-- tional view through the hopper and delivery spout and valve taken on the line A-A of Figure 4.

Figure 4 is a plan view of the inner face oi the. hopper bottom, said bottom being broken away to show the relation of the valve or shutter the-reto.

v Figure 5-is a side elevation showing a' modified form of hopper for use on `trucks or vehicles not provided with a running board.

' Like `numerals of reference indicate corresponding parts in the various figures.

Referring to the drawings 1 and 2 are sand storage receptacles, shown in drawings as being in the form of elongated tapered boxes secu-red .to the under sides of the runnin boards 3 of the vehicle but it must be un' erstood that these storage receptacles rllhe bottoms oil theihoppers 4 and 5 are sloped downwardly towards the delivery ends, soas to insure an adequate supply of sand at said delivery end, and are provided with a series of openings 6 therelcross through which the sand is adapted to- 7 are spouts with which each of the hoppers is provided at its delivery end, the sides of said spouts adjacent to the wheels being shaped to substantially follow the contour of the wheels for the greater portion of their 8o length and terminate in outwardly curving j lips 8 while the opposite walls slope downwardly in a straight line towards the rear walls and terminate slightly short of the lips 8 leaving a narrow slit 9 in each spout a5 through which the sand passes from the hopper above to the road surface directly in advance of the wheels.

10 are plates supported in any desired manner slightly below the bottoms of the 9o hoppers and extending from the extreme outer ends of said hoppers to a. point considerably in advance of the openings. 6 in said bottoms and being provided with a series of openingsll registering with said an openings 6 but being of considerably greater dimensions than said openings 6.

12 are plates or valves slidably arranged between the bottom oi' the hoppers respectively and the corresponding plates 10, said valves being adapted to project past the front ends of the plates 10 and being provided with downwardly projecting lugs 13 to the front sides of which are secured hooks 14.

15 are springs secured tothe lugs 13 from the valves 12 and to lugs '16 from the plates l0 and exerting a pull on said valves to llllli hold them normally to the rear ends of said hoppers to prevent the escape of the sand from said hoppers.

17 are cables secured to the hooks 14 of the lugs 13 and operating through brackets 18 secured to the bottoms of the hoppersand being secured together as at 19 substantially centrally of the vehicle body and extending in a single cable or rod 20 through the car body and terminating in any convenient location, preferably in close proximity to the steering rod. The end of the cable or rod 20 may of course be provided with any convenient form of handle with which to exert a pull on same for drawing the valves forwardly to permit of the sand passlng through the openings in the hopper bottoms and the corresponding plates 10.

The cable or rod 2() may also be supported at intervals by brackets 2l or by other desired means to hold same to its proper position.

If desirable curved tubular members 22 may be rigidly supported within the brackets 18 for the purposeof loosely accommodating the cables 17 to reduce to a minimum the wear on said cables.

23 are discs rigidly secured to the cables 17 a dista-nce to the rear of the tubes 22 slightly greater than the distance between the outer ends of the hoppers and the front edges of the sand openings 11 in the plates 10, said discs being of greater dimensions than the openings in said tubes and forming stops to limit the opening movement of said valves.

24 is an apron shown in dotted lines as being suspended from the outer edge of the running board to conceal the storage receptacle.

In Figure 5 a modified form of storage receptacle and hopper is shown, this construction bein on trucks am? other forms of vehicles not provided with running boards from which to suspend the various parts.

The storage receptacles 25 are preferably of conical formation and areV supported slightly in advance of the wheels of the vehicle. The bottoms of said receptacles are provided with screens 26 thereacross which tend to relieve the hoppers of the weight of the sand but which at the same time permit of an adequate supply of sand passing into the hoppers 27 which are the construction of said hoppers being similar-to that of the hoppers l and 2 as described hereinbefore. Y

The valves in this form of construction adapted particularly for use located therebelow,

are preferably operated by means of a toggle mechanism consisting of a transverse rod 27 rotatably mounted in bearings in brackets 28 supported from the vehicle frame, cra-nk levers 29 connecting the ends of said rod with the adjacent valve and a rod 30 rigidly secured centrally of said rod and projecting downwardly therefrom and having secured to the lower end thereof a rod or cable 31 which projects through the car body and is provided with a handle or other operating means located within convenient reach of the operator.

Owing to the shape of the storage receptacles the sand will How therefrom into the hoppers as fast as the sand already in said hoppers is released therefrom and in the use of the invention it is only necessary when desirable to provide a gripping surface to pull on the handle or other means with which the cable or rod 20 is provided and this has the eli'ect of drawing the valves forwardly and permits of the sand falling through the openings in the hopper bottoms and the plates l() into the spouts 7 which defiect it on to the roadway directly in front of the driving wheels. As soon as the cable 2() is released the springs l5 force the valves to their normal positions over the openings 11 and thus effectually prevent the escape of sand.

While I have thus described the preferred construction, combination and arrangement of parts which constitute the present invention, it is obvious that others skilled in the arts to which this appertains, may make various changes without departing from the spirit and scope of the invention asl contained in the claim for novelty following.

What I claim is The combination in a vehicle, of a pair of elongated storage receptacles secured to the under sides of the running boards respectively, said receptacles increasing in depth to their rear ends and terminating in substantially spout shaped hoppers, the top walls of said hoppers and the bottom walls of said receptacles being spaced and being provided with sand outlets, valves interposed between said hoppers and said receptacles respectively and spring held to their closed positions, and means for operating said valves.

Signed at the city of Toronto, Province ofl Ontario, this 2nd day of October, 1919.
